Bayesian Joint Velocity and Impedance Inversion via Diffusion Models Conditioned on Common Image Gathers
Yunlin Zeng, Huseyin Tuna Erdinc, Felix J. Herrmann
We present a multi-parameter simulation-based inference framework for joint Bayesian recovery of subsurface velocity and acoustic impedance from seismic data. A score-based diffusi…

Full-waveform variational inference with full common-image gathers and diffusion network
Yunlin Zeng, Huseyin Tuna Erdinc, Rafael Orozco +1
Accurate seismic imaging and velocity estimation are essential for subsurface characterization. Conventional inversion techniques, such as full-waveform inversion, remain computati…
